SY26168/SY26169 High Efficiency, 12A, 16V Input Synchronous Step-Down Regulator General Description The SY26168 and SY26169 are high efficiency synchronous step-down DC-DC regulators that feature internal power and synchronous rectifier switches, and are capable of delivering 12A continuous output current over a wide input voltage range from 2.7V to 16V. The output voltage is adjustable: SY26168 from 0.9V to 5.5V and SY26169 from 0.6V to 5.5V. Silergy’s proprietary Instant-PWM™ fast-response, constant on-time (COT) PWM control method supports high input/output voltage ratios (low duty cycles) and responds to load transients within approximately 100ns while maintaining a near-constant operating frequency over line, load, and output voltage ranges. This control method provides stable operation without plex pensation, even with low ESR ceramic output capacitors. The stable internal reference (VREF) provides ±1% accuracy over TJ = -40°C to 125°C, and the differential input sense configuration allows the feedback sensing at the most relevant load point. Internal 13.3mΩ power and 3.8mΩ synchronous rectifier switches provide excellent efficiency for a wide range of applications, especially for low output voltages and low duty cycles. Cycle-by-cycle current limit, input undervoltage lockout, internal soft-start, output undervoltage (UVP) and overvoltage (OVP) protection, and thermal shutdown provide safe operation in all operating conditions. The SY26168 and SY26169 is available in a pact QFN3×4 package.
